In terms of care and maintenance, there is one golden rule I suggest you follow:
Keep the ink in your pen fresh. If you leave it for a long period of time unused, flush out the ink, use normal water to draw and expel water to wash/flush out the ink feed system.
That probably is one of the best things you can do on a regular basis to keep your fountain pen functioning at a top notch level.
If you use cartridges, then remove the cartridge and hold the nib section of the pen under running water to flush the feed out.
